Abstract

A display device is provided. The display device may include a display panel including a front substrate and a back substrate, a frame positioned behind the display panel, an optical layer positioned between the display panel and the frame, and a supporting film attached to the display panel and connected to the frame. The display device may also include a fastening device for fastening the supporting film to the frame. The display panel may include a front polarizing film attached to a front surface of the front substrate, and a back polarizing film attached to a back surface of the back substrate. The supporting film may be attached to the back polarizing film.

Claims

1. A display device comprising:

a display panel;

a frame provided at a rear of the display panel;

a film including a first portion attached to at least a portion of the display panel, a second portion positioned at a side of the frame and a third portion positioned at a rear of the frame;

a plate fixed to the frame by a fastening member, the third portion of the film being fixed on a part of the plate; and

a pressure plate pressing the third portion of the film at the rear of the frame,

wherein the third portion of the film is positioned between the frame and the pressure plate.

2. The display device of claim 1, wherein the third portion of the film is attached on a rear surface of the plate.

3. The display device of claim 1, wherein the pressure plate includes at least one depression area.

4. The display device of claim 1, further comprising a back cover positioned on the rear of the frame and covering the pressure plate.

5. The display device of claim 1, wherein the plate is bent such that the third portion of the film is attached to the part of the plate.

6. The display device of claim 5, wherein a bent portion of the plate is fixed to the frame by the fastening member.

7. The display device of claim 1, wherein the pressure plate includes a first area, a second area that extends and bends from the first area and a third area that extends and bends from the second area, the third area being parallel to the first area.

8. The display device of claim 1, wherein the second and third portions of the film are extended from edges of the first portion of the film, the edges being opposite edges on the film.

9. The display device of claim 1, wherein the first portion of the film includes a transparent area to transmit light of the backlight device.

10. The display device of claim 1, wherein a light transmittance of at least one portion of the film is different from a light transmittance of at least another portion of the film.

11. The display device of claim 1, wherein the backlight device includes a plurality of light source modules and at least one optical sheet.

12. The display device of claim 11, wherein the plurality of light source modules are fixed to the frame and disposed separately from each other and connected electrically.

13. The display device of claim 1, further comprising a backlight device provided on the rear of the display panel, the backlight device comprising a plurality of light source modules provided along at least one side of the frame, and a light guide plate facing the plurality of light source modules.

14. The display device of claim 1, wherein the second portion of the film extends from the first portion and the third portion extends from the second portion, and

the second and third portions extend from at least one of side edge and top edge of the film.

15. The display device of claim 1, wherein the pressure plate and the frame are fixed by a fastening member passing through a first hole formed on the pressure plate and a second hole formed on the frame.

16. The display device of claim 1, wherein the pressure plate directly contacts with at least a portion of the third portion of the film.

17. The display device of claim 1, wherein the pressure plate is only positioned on the rear of the frame.

18. The display device of claim 1, wherein the pressure plate is in plural.

19. The display device of claim 1, wherein the pressure plate is in plural and each of the pressure plates are separately provided along an edge of the frame.
